2. In a machine such as described, the combination with side frames andspindles, of carrying-wheels having projecting hubs journaled on saidspindles, the inner end of said hubs contacting said frames, a lateralextcn sion forming an annular recess at the other end of said huh,driving-gears for the sweeper having their hubs journaled on thecarrying- .adapted to carry the respective ends ol.
